BREAST-PUMP.

Specieation of Letters Patent.

Patented Feb. 15, 1910.

Application filed February 23, 1909. Serial No. 479,570.

To all whom it may concern:

Be it known that I, I-Iowniu) V. BRUMLEY, a citizen ot' the UnitedStates, and resident of the borough oit- Brooklyn, county of Kings, cityand State of New York, have invented certain new and useful Improvementsin Breast-Pumps, ot' which the :t'ollowing is a specification.

My invention relates to breast pumps and has tor its object to constructa pmnp ol this description in such a manner that the interior will befree it'rom angles so as to be easily and thoroughly cleaned and whichmay be applied to the breast in any position and still retain lthe milkagainst entrance to the bulb. I i'urther attach the bulb to the neck ot'the receptacle in such a manner as to secure an air tight joint andconsequent perfect suction.

My invention will be fully described hereinafter and the Jfeatures of'novelty will be pointed out in the appended claim.

Reference is to be had to the accompanying drawings in which- Figure lis a part elevation and part central sectional view ot my improved pump;Fig. 2 is a cross section thereotl on the line 2N2 of Fig. l; and Fig. 3is a perspective view ot the bulb.

In the drawings A represents the flaring mouth otl the pump which isapplied to the breast and which is connected and communi- Cates with thebulbous receptacle D. The said receptacle B formed with a screwthreadedtubular neck C adapted to receive the screw-threaded sleeve or collar D.The rubber bulb E is provided with a neck portion E formed with anannular flange E2 arranged to abut against the end of the neck C. Thecollar D is provided with an annular flange D loosely surromuling theneck portion E of the rubber bulb E and adapted to engage the flange D2thereof. Thus as the collar D is screwed up on the neck (l, the flangeE2 will be firmly clamped between the end of lthe neck C and the flangeD ot the collar D. The connection between the rubber bulb and the neck Cis thus absolutely air tight and a perfect suction is secured as thebulb E is operated. It will be noticed that the inner diameter of theneck portion E is less than the inner diameter of the neck C of thereceptacle. A sort of protecting rim E3 is thus formed which preventsthe contents of the bulbous receptacle from easily running into the bulbE. The bulbous receptacle B is circular or continuous in cross-sections0 that it is unnecessary to carefully position the pump on the breast,as no matter what the position of the pump some part of the saidreceptacle B will be in a depending position to receive the milk. Themore the collar D is screwed up on the neck l, the better will be theconnection between said neck and the rubber bulb. The parts o1 myimproved pump may be easily separated for the purpose of cleaning andowing to the interior lorm of the pump and the absence ol angles thiscleaning is easily accomplished and is thorough in its results. Itshould be noted that the flaring mouth A ot' my improved pump is of suchsize and shape that it will always be clear ol the breast nipple whetherheld in the hand or allowed to hang it'ree.

I claim as my invention: I

A breast pump comprising a one-piece receptacle and a collapsiblesuction bulb, said receptacle having a central spherical portionprovided with an outwardly flared neck or tubulature adapted to surroundwithout touching the nipple joined to one side thereoli, and acylindrical neck joined to the other side thereo'l, both tubulature andneck having a diameter ot the sphere as their central axis and the neckhaving an external screw thread formed thereon; and the suction bulbbeingl spherical in shape and provided with a neck having an externalannular f'lal'lge at the outer extremity thereof, the outer diameter ol.said flange being substantially equal to that ot the neck ol? thereceptacle and itsl internal diameter substantially less than theinternal diameter ot the neck of the receptacle; said receptacle andsaid suction bulb being clamped together with the outer ends of theirtwo necks abutting and so held by a tubular cap provided with a screwthread to fit the threaded neck of the receptacle and an inwardlyprojecting flange at one end to engage the flange of the suction bulbneck, as and for the purpose de scribed.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
